The segments shown are dilations of each other about the origin. Which statement could be true? The coordinate (1, 0) is from a dilation using the scale factor of One-fifth. The coordinate (5, 0) is from a dilation using the scale factor of 4. The coordinate (1, 0) is from a dilation using the scale factor of 5. The coordinate (5, 0) is from a dilation using the scale factor of One-fifth.

Answer:

28:35

Step-by-step explanation:

Since Rita is trying to prove that the two triangles are similar, she will be looking for corresponding sets of sides that have an equivalent ratio. Therefore, since for the big triangle she uses sides PQ and PR, the corresponding sides on the smaller triangle would be PS and PT, which have a ratio of 28:35. Hope this helps!

The statement is completed by 28 :35, the correct option is B.

Two triangles of the same shape are said to be similar when their corresponding sides are proportional.

The triangle RPQ

The length of PS is equal to 28

The length of SQ is equal to 2x

The length of PT is equal to 35

The length of TR is equal to 60

The triangles  SPT and QPR are proved to be similar in Step 4 by the property that corresponding sides of similar triangles are in proportion.

(2x + 28):95 =28 :35

Therefore, the statement is completed by 28 :35, the correct option is B.

Answer:

x-18

Step-by-step explanation:

Answer:

1 ) m∠ 1 = 72°, m∠2 = 108°,

2 ) m∠ 1 = 22.5°, m∠2 = 67.5°

Step-by-step explanation:

Question 2 ) Assuming these are supplementary angles, we know that their measures form a linear pair that add to 180°;

let us assign these angles as 1, and 2 ⇒ m∠ 1 + m∠ 2 = 180,

with the given ratios 2 to 3, we can say x ⇒ one part of measure, so that ⇒ 2x + 3x = 180,

2x + 3x = 180 ⇒ combine like terms,

5x = 180 ⇒ divide either side by 5,

x = 36°

If this is so, m∠ 1 = 2x = 2 * ( 36 ) = 72°, and m∠ 2 = 3x = 3 * ( 36 ) = 108°;

Solution; m∠ 1 = 72°, m∠2 = 108°

Question 3 ) If it is known that two angles are complementary to one another, we can say their measures add to 90°;

let us one more, assign these angles as 1 and 2 ⇒ m∠ 1 + m∠ 2 = 180,

knowing that the measure of one angle is 3 times that of the other angle we can derive the ratio 1 : 3 in the manner smaller ∠ measure : bigger ∠ measure so that ⇒ x + 3x = 90,

x + 3x = 90 ⇒ combine like terms,

4x = 90 ⇒ divide either side by 4,

x = 22.5

If this is so, m∠ 1 = x = 1 * ( 22.5 ) = 22.5°, and m∠ 2 = 3x = 3 * ( 22.5 ) = 67.5°;

Solution; m∠ 1 = 22.5°, m∠2 = 67.5°

Answer:

y= 3x +4

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx +c, where m is the gradient and c is the y-intercept.

To find the value of m, use the gradient formula below:

[tex]gradient = \frac{y1 - y2}{x1 - x2} [/tex]

Gradient

[tex] = \frac{4 - ( - 8)}{0 - ( - 4)} \\ = \frac{4 + 8}{0 + 4} \\ = \frac{12}{4} \\ = 3[/tex]

Subst. m=3 into the equation.

y= 3x +c

To find the value of c, substitute a coordinate.

When x=0, y=4,

4= 3(0) +c

c=4

Thus, the equation of the line is y= 3x +4.

Answer:

We know that, for a right triangle:

Cos(A) = (adjacent cathetus)/hipotenuse

sin(A) = (opposite cathetus)/Hipotenuse.

If we are in a right triangle inside the unit circle, we have that hypotenuse = 1.

Now, when you draw the unit circle, now from the center of the axis you must draw a straigth line (that forms an angle of 120° with the x-axis), and in the point where it cuts the unit circle we do 2 things.

from this point, you can draw a parallel line to the y-axis, the point where this line touches the x-axis is the value of the cosine.

Now you draw a line that is parallel to the x-axis (remember that the line must pass trough the point of before), the point where this line cuts the y-axis is the value of the sine

You should get:

sin(120°) = 0.87

cos(120°) = -0.5

Step-by-step explanation:

2.7 * 10 ^-5 / 9 * 10 ^-6

First divide the numbers

2.7 / 9 = .3

Then divide the exponents

10^-5 / 10 ^ -6

When we divide exponents we subtract

10^(-5 - -6) = 10 ^1

.3 * 10 ^1

But scientific notation has a number between 1 and less than 10

Move the decimal 1 place to the left, so we subtract 1 from the exponent

3 * 10 ^ (1-1)

3 * 10 ^0

Answer:

x + 8 + 12 + 11 = 43

Step-by-step explanation:

The perimeter is the length of the 4 sections of fencing.

If x represents the fourth section and the perimeter is 43, then

x + 8 + 12 + 11 = 43, that is

x + 31 = 43 ( subtract 31 from both sides )

x = 12

The length of the fourth section is 12 ft

Answer:

Answer:

Area of rectangle PLUM = 75.00 square units

Step-by-step explanation:

Since diagonal of rectangle divides the rectangle into two equal triangles,

Therefore, area of the rectangle PLUM = 2× area of triangle PLM

By the mean proportional theorem,

In ΔPLM,

AP² = AM × AL

6² = AM × 8

AM = [tex]\frac{36}{8}[/tex]

AM = 4.5 units

Area of PLM = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]

                     = [tex]\frac{1}{2}(ML)(AP)[/tex]

                     = [tex]\frac{1}{2}(8 + 4.5)(6)[/tex]

                     = 12.5 × 3

                     = 37.5 units²

Now area of rectangle PLUM = 2×37.5 = 75 units²

Therefore, area of the rectangle is 75.00 square units.

Answer:

45 , 135

Step-by-step explanation:

LET ONE ANGLE BE x AND OTHER ANGLE BE 45+2x

since they are supplementary angles ,

x+2x+45=180

3x = 180 -45

3x = 135

x = 135/3

x =45 degree

therefore measure of one angle = 45 degree and other angle angle  = 2*45+45 = 90+45 = 135 degree

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

The profit made is equal to 2.25-2.25 which is 0.

The situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero. which is the correct answer would be an option (B).

Distance is defined as the product of speed and time.

As per option (A),

The overall change in temperature = 10 - (-10) = 20 degrees

As per option (B),

The profit made is equal to 2.25 - 2.25 = 0 which is zero.

As per option (C),

The overall change in altitude = 21 - 0 = 21 kilometers

As per option (D),

The total distance traveled by person = 3.1 + 3.1 = 6.2 miles

Thus, the situation "the total profit is made when a person buys an item for $2.25 and then sells the item for $2.25" is result in a final value of zero.

Hence, the correct answer would be option (B).

Step-by-step explanation:

To find the area of a trapezoid you and the little base and the big base. then divide the answer by two. Then you multiply the answer you just got by the height.

Equation:

145+225=370

370/2=185

185*80=14800

Area of the park is 14800 square yards

A quadrilateral with at least one pair of parallel sides is called Trapezoid

Area is the quantity that expresses the extent of a region on the plane or on a curved surface.

Given,

Short base a = 145 yards

Long base b = 225 yards

Height h = 80 yards

Area of the park = [tex]\frac{a+b}{2}h[/tex]

Area of the park =[tex](\frac{145+225}{2})80[/tex] = 14800 square yards
